Explain how data are sent through the Internet via packets.
CSN-1.C.1 Information is passed through the Internet as a data stream. Data streams contain chunks of data, which are encapsulated in packets.
CSN-1.C.2 Packets contain a chunk of data and metadata used for routing the packet between the origin and the destination on the Internet, as well as for data reassembly.
CSN-1.C.3 Packets may arrive at the destination in order, out of order, or not at all.
CSN-1.C.4 IP, TCP, and UDP are common protocols used on the Internet.
